    Unable to view remote LAN folders in different extension formats (ext4, etc). TreeSize can see them well.

    It's Open Source, Free, and does the exact same thing but faster, yes you may not have the features of the PREMIUM version of Tree Size, but we are comparing the free version.

    WizTree is faster and much more accurate than Treesize as it properly handles hard linked files (doesn't count them more than once) so the total allocated size reported by WizTree will actually match the space used on the drive as reported by Windows.

    Much faster than all others I've tried, even on network shares. The visualization looks very similar to windirstat, almost identical.

    It is very fast, even on remote disks. I use it to manage my Google Drive through Google File Stream.
